CHURN.

SPECIFICATION forming part of Letters Patent No. 430,654, dated J' une 24, 1890.

Application iiled March 18, 1890. Serial No. 344,309. (No model.)

To all whom it may concern:

Be it known that I, ERNEST KELLERsTRAss, of Excelsior Springs, Olay county, Missouri, have invented certain new and useful Improvements in Ohurns, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to churns for churning butter; and it consists in the following combination of different parts, hereinafter more fully described, and set forth in the accompanying drawings, in which- Figure l is a perspective view of the invention. Fig. 2 is a longitudinal sectional View. Fig. 3 is a cross-sectional view. Fig. 4 is a detail view showing the construction of the upper portion of the perpendicularshaft. Fig. 5 is a detail View showing the spring-arm and the shaft J drawn up and out of their operative position.

It will be seen at Fig. l in constructing my invention I use a square vessel so constructed that it will hold milk or cream without leaking. In this particular case I use a vessel made square, with a molding around the top, forming a depending flange around the same. Then I make my lid in two pieces, making one piece about as large again as the other. The lid is then dropped in position on the churn, and the small buttons attached to the molding, forming the depending flange with the top of the churn, are turned around, extending over the edges of the lid, holding it in position. On the smaller piece of the lid I use a knob to remove that portion at any time during the churning process, so that the cream or milk may be seen at any stage of churning. Two uprights D D are rigidly secured to the larger portion of the lid. On the upper ends of said uprights is mounted a shaft carrying a gear-wheel G, attached thereto, said gear-wheel meshing with a cog-wheel L, by means of which the dasher-shaft, extending down to the bottom of the churn, is rapidly revolved. It will be seen in Fig. 5 that in order to detach the lid from the shaft I have provided a longitudinal sleeve. The upper portion of the shaft,

which is secured to the small cog-wheel, is l provided with a loop made of a suitable-sized piece of wire, the top end of which g passes through a perforation made in the shaft, and suitably riveted to hold it in position, at the same time it works loosely. The bottom end of the spring-arm when in position is inserted in a perforation at the lower portion of the sleeve, holding the machinery and lower portion ot' the main shaft together, the shaft resting over a pivot at the bottom of the churn. I then take the portion of the lid which has the machinery mounted thereon. The top portion of the shaft is then inserted in the sleeve, drops down until the top portion of the wire lever is in the slot at the top of sleeve, and then before the operation of churning is commenced the churn is iilled sufficiently full of cream. The bottom portion of the springarm is thensprung into a perforation, (seen at the bottom end of the sleeve,)' which holds it firmly in position during the churning operation.

In Fig. l, G is the gear-wheel. F is the horizontal shaft; II, the crank; K,the journal end of upright shaft; L, small cog-wheel; d, the extended arm in connection with the portion holding the small cog-wheel in position; D D, uprights; e, two extended lugs in which is a small lag-pulley holding large cog-wheel in position.

o' is a slot in the upper end of the sleeve l, in which lever M drops when in position; J, the portion of shaft which drops into sleeve in a perforationin the lower end of the sleeve in which the right-angled lower end of springarm is inserted` B is the large portion of the churn-top.

Otis the small portion of the top; c, knob; b, buttons, which hold the top in position. p is a metallic fiange rigidly secured to the under side of the churn-top, through which shaft passes.

'n is a rivet, which holds the lower portions of the sleeve to the main shaft; N, the main shaft; O O, the dashers, which are made of any suitable length, V shape in cross-section, and attached to the main shaft in a spirallike form. g

P is a pivot extending through the bottom of the churn, formingabearing for the dashershaft.

Having thus fully described my invention, what I claim, and desire protection in by Letters Patent, is-

In a churn, the main shaft having an extension I, provided with a slot 7l and recess fm, the shaft K, the sleeve J, secured around the shaft K, the spring-arm secured to said 5 sleeve and shaft and engaging' slot t' and recess m, the cog-Wheel L, secured to the shaft K and meshing With a gear-Wheel, a small idle- Wheel, which holds the gear-Wheel in position, nprights D D and projections cl and c on the 1o same, a suitable bearing for the gear-Wheel,

the said shaft K, and sleeve J, located'inside ofthe extension I of the main shaft, substantially as described.

In testimony whereof I affix my sign-at ure in presence of two Witnesses.
